How to save a file that data as it can be deleted, edited in future?

Question

I am new to iPhone development. I have a question would like to ask. which is the best way to save data into a file? That later, I could get the data from it, and edit it, add new one and delete easily.

Such as: I have a library system which store information about books. A book will have:

name, publisher, date published, author, price...

I thought of file plist. But I think file plist is readonly. I can't edit anything in there right? Please help me out. I am so thankful.

Answer 1

You could use a plist, you would have to read the entire contents into memory and then re-write it at the end of processing. However, Core Data is exactly what you want for this.

Answer 2

I think CoreData is what you want.
